Plakats are short finned, but can be different tail types, which is what the question was about I believe :)

Can't really tell if he is a HMPK as his fins aren't spread open enough for me to tell. He isn't a CTPK.. could be a traditional PK, which is what I am thinking as his tail looks more rounded than the other two variations PKs come in.
First time breeding?

This fish seems very off balance to me.
I'm not going with show fish qualities because his line would need generations of work to get there.
Anyway, his body seems to be really short and there's something going on with his spine at his caudal base. IDK if you should breed him at all but if you do decide to, please fatten him up first.
